Perlite instead of Vermiculite
    #2262651 - 01/22/04 01:36 PM (13 years, 4 months ago)

I am low on vermiculite and I have an excess of perlite. Would it be possible to substitute perlite for the vermiculite in the top layer of a PF tek jar? I am not talking about the substrate, just the filter layer on the top.

Maybe it will be workin', but I guess that vermiculite is one
of the best "contamination' layer" around...
Don't know how much perlite can work as the vermiculite regardin'
the contam.  :confused:
If you are going to make this substitution, I'd
put one more foil of aluminium and wouldn't be checking every day how
the jars are goin'; just to avoid some contamination "opportunities",
you know.

If you CAN'T wait for the arrive of vermiculite... try.  :tongue:

use a coffee filter under the lid, then tape off the holes after injection.

I wouldnt use perlite as the top filter for the jars.

Ive done it a couple times..just be real careful, but i would just leave off the top filter layer..and either put a coffee filter over over the top of the outside of the jar with a rubber band holding it secure to the jar...

or get some tyvek...or a micron filter

hope that will help

Perlite would not work well for a pf top seal. You really can't substitute 1 for the other in any situation. I'm not a fan of the pf verm seal anyway for a number of reasons. If I were you I would get a 99 cent bag of polyfill and use that for filters like this...
